At Disorientation the headliner usually doesn't go on stage until around 9 - 9:30.
For some reason I couldn't edit my previous post. Maybe I'm blind and can't see the edit option.
Anyways, yes, like I said the headliner goes on stage around 9 - 9:30 - ish. It's a pretty long wait considering the gates open at what...3:30? if i'm not mistaken. However, I'd stick around and check out the opening acts. Specifically:
Faber - needs no introduction, if you reside in Greater Vancouver area you probably know (unless you live under a rock) that they won CFOX Seeds this year.
Hedley - saw them at the PNE the other day, and was quite really very impressed/pleasantly surprised. The video that's being played on Much does them no justice whatsoever. Some familiar faces, too - Crippin (Bif Naked), Tommy MacDonald (ex-Jar, Flybanger), Dave Rosin. All 3 of them, as you might recall, used to be in Everything After before it passed away into oblivion.
The Heck - if you haven't seen them yet, you might wanna check them out - the frontman is a fruckin' guitar god (and that's at the tender age of 18)
